German Greens party deputy Hans-Christian Stroebele travelled to Italy today and met with three Germans hospitalised after the demonstrations at the G8 summit in Genoa.
He told AFPthat all three had "serious head wounds".
Mr Stroebele said they were arrested in a police raid on a hostel for anti-globalisation demonstrators set up in a school.
The deputy said all three told him that they offered no resistance when the Italian police burst but that they were neverthless beaten to the ground with clubs.
"These incidents remind me of the military dictatorship in Argentina," said Mr Stroebele, a lawyer with a radical political past.
Mr Stroebele, who was accompanied by another Greens deputy, Annelie Buntenbach, and the German consul-general, said he intended to visit another injured demonstrator in hospital this evening.
Tomorrow he plans to visit Germans held in five different jails following their arrest amid the anti-globalisation demonstrations.
According to the German Foreign Ministry, 58 Germans were still detained today following the mass arrest of activists in Genoa, and nine injured Germans were still in hospital.
